At Datadog, we leverage AI across our observability platform to improve monitoring, speed up incident resolution, and ensure data reliability for cloud applications.

Datadog’s Deployment Gates team builds customer-facing systems that decide whether software should ship to production. Deployment Gates sit directly in customers’ CI/CD pipelines and use observability data to answer one of the hardest questions in software delivery:
Given everything we know right now, is this deployment safe to proceed?

In this role, you will:

• Work on an analysis service that prevents incidents by detecting faulty software changes in production before they reach clients

• Lead the design of progressive deployment automation, starting with zero-setup, conservative AI rules and evolving toward adaptive gates that learn from incidents and organizational patterns
• Design the foundation for autonomous remediation, connecting what changed in code to what broke in production, from blocking and rolling back unsafe deployments to proposing fixes and enforcing policies

This is a highly product‑minded engineering role: you’ll work from problem discovery and UX all the way to reliable, scalable production systems.

At Datadog, we place value in our office culture - the relationships that it builds, the creativity it brings to the table, and the collaboration of being together. We operate as a hybrid workplace to ensure our employees can create a work-life harmony that best fits them.

What you’ll do:

• Build AI-driven deployment gates: Design and ship decision systems that evaluate customer deployments using CI/CD context and Datadog telemetry, producing safe, explainable allow/block outcomes
• Own evals and rollout: Define precision, recall, and trust metrics; build offline and online evals; validate changes in shadow mode; and safely promote improvements to enforcement
• Design for robustness and safety: Implement conservative defaults, guardrails, fallbacks, and human-in-the-loop paths so gates behave predictably under noisy or incomplete data
• Partner closely with Product: Work hand-in-hand with the Product Manager to translate customer problems, adoption signals, and roadmap goals into concrete technical decisions and iterations
• Integrate across the Datadog platform: Partner with internal AI teams building the Faulty Deployment Detection pipeline, as well as teams working on LLMs and AI agents
• Own production systems: Build and operate reliable backend services that run in the critical path of customer deployments, and be on-call for those services

Who you are:

• A Product‑minded engineer who ships AI to production
• You have 5+ years experience with backend systems and microservices performance: tracing, latency breakdowns, concurrency, and resiliency patterns
• You are proficient in a modern programming language; strong API/service design; production ops (monitoring, alerting, on‑call rotation)
• You have proven experience delivering software based on LLM/agent features to production
• You are comfortable owning user journeys, iterating from prototype → alpha → GA, and measuring impact with clear product metrics
• An End-to-end AI implementation owner: You understands the end-to-end LLM product lifecycle
• Fluent with offline/online evals for AI systems
• You have demonstrated ability to use AI coding tools in day-to-day workflows and validate, critique, and refine AI-generated output

Bonus Point:

• Experience with Continuous Delivery tools (i.e. ArgoCD / Argo Rollouts, Spinnaker, Octopus Deploy)
• Exposure to planning/agent frameworks, tool‑use orchestration, RAG, and retrieval/indexing for observability data
• You’re motivated to push the boundaries of how AI can improve software engineering best practices and contribute to building AI-enabled products

We're looking for a hands-on builder to join Bolt for Business and drive agentic workflow automation — someone who loves turning commercial problems into working automations and wants to see their code directly move sales metrics.

With over 200 million customers in 50+ countries, Bolt is one of the fastest-growing tech companies in Europe and Africa. And it's all thanks to our people.

We believe in creating an inclusive environment where everyone is welcome, regardless of race, colour, religion, gender identity, sexual orientation, age, or disability.

Our ultimate goal is to make cities for people, not cars, and we need your help to achieve this mission!

As a GTM Automation Analyst within Bolt for Business - AI Centre of Excellence, you'll spend the majority of your time building — designing and deploying workflow automations and AI integrations that help our Sales and Account Management teams work faster and smarter across markets.

You'll work independently to build on platforms like n8n, write the logic that makes them tick, and connect them into Salesforce and the rest of our commercial stack. Over time, you'll develop a feel for the full lifecycle of a production automation — from scoping and build through to monitoring and iteration.

This is a great role if you've built automations before and want to go deeper, or if you're coming from a technical background and want to apply your skills to a fast-moving commercial environment.

• Build and maintain workflow automations using platforms like n8n, Zapier, or Make — writing JavaScript for logic and data transformation, and integrating with REST APIs across Salesforce and other internal and external tools.
• Integrate LLM APIs (e.g. Claude, GPT) into commercial workflows, including prompt design, output validation, and basic agent patterns applied to use cases like lead qualification, content generation, and rep prioritisation.
• Query and transform CRM and commercial datasets using SQL to support automation inputs, scoring logic, and reporting — keeping data consistent across connected systems.
• Add logging, error handling, and monitoring to every automation you ship, so they run reliably in production rather than just in demos.
• Track the impact of what you build — time saved, conversion rates, orders per rep — and iterate based on what the data shows.
• Work with your manager and commercial teammates to understand the problems you're solving before you build, and flag technical constraints or tradeoffs clearly.
   

• You've built workflow automations using a platform like n8n, Zapier, or Make — ideally at least one that's running in a real environment, not just a prototype.
• You're comfortable writing JavaScript for workflow logic and working with REST APIs and webhooks.

We're looking for a hands-on builder to join Bolt for Business and drive agentic workflow automation — someone who loves turning commercial problems into working automations and wants to see their code directly move sales metrics.

With over 200 million customers in 50+ countries, Bolt is one of the fastest-growing tech companies in Europe and Africa. And it's all thanks to our people.

We believe in creating an inclusive environment where everyone is welcome, regardless of race, colour, religion, gender identity, sexual orientation, age, or disability.

Our ultimate goal is to make cities for people, not cars, and we need your help to achieve this mission!

As a GTM Automation Analyst within Bolt for Business - AI Centre of Excellence, you'll spend the majority of your time building — designing and deploying workflow automations and AI integrations that help our Sales and Account Management teams work faster and smarter across markets.

You'll work independently to build on platforms like n8n, write the logic that makes them tick, and connect them into Salesforce and the rest of our commercial stack. Over time, you'll develop a feel for the full lifecycle of a production automation — from scoping and build through to monitoring and iteration.

This is a great role if you've built automations before and want to go deeper, or if you're coming from a technical background and want to apply your skills to a fast-moving commercial environment.

• Build and maintain workflow automations using platforms like n8n, Zapier, or Make — writing JavaScript for logic and data transformation, and integrating with REST APIs across Salesforce and other internal and external tools.
• Integrate LLM APIs (e.g. Claude, GPT) into commercial workflows, including prompt design, output validation, and basic agent patterns applied to use cases like lead qualification, content generation, and rep prioritisation.
• Query and transform CRM and commercial datasets using SQL to support automation inputs, scoring logic, and reporting — keeping data consistent across connected systems.
• Add logging, error handling, and monitoring to every automation you ship, so they run reliably in production rather than just in demos.
• Track the impact of what you build — time saved, conversion rates, orders per rep — and iterate based on what the data shows.
• Work with your manager and commercial teammates to understand the problems you're solving before you build, and flag technical constraints or tradeoffs clearly.
   

• You've built workflow automations using a platform like n8n, Zapier, or Make — ideally at least one that's running in a real environment, not just a prototype.
• You're comfortable writing JavaScript for workflow logic and working with REST APIs and webhooks.
• You have some experience integrating LLM APIs into workflows and are comfortable working with Claude Code.
• You have solid SQL skills and can navigate a CRM like Salesforce well enough to extract what you need.
• You're studying or have studied Computer Science, Engineering, or a related field — or you've built enough on your own that it shows.
• Exposure to Python, Clay, GitHub, or AI agent frameworks is a plus, but not required.

Experience is great, but what we really look for is drive, intelligence, and integrity. So even if you don't tick every box, please consider applying!

• Accelerate your professional growth with unique career opportunities.
• Enjoy a rewarding salary and stock options, knowing that as Bolt succeeds, so do you.
• Take care of your physical and mental health with our wellness perks.
• Celebrate 5 years at Bolt with a 1-month paid sabbatical to recharge.
• Connect with colleagues at annual company events and smaller team gatherings.
• Balance flexibility and in-person collaboration with our hybrid model, including at least 12 monthly in-office days.
